Inventor Patented July 7, 1936 UNITED STATES PATENT OFFICE FIREARM Application .May 25, 1934, Serial No. 727,559 In Germany May 27, 1933 6 Claims.

This invention relates Yto a fire-arm of novel construction. Fire-arms are already known in the form of a .box-like casing, which can be tted to a belt or the like. With such casings the 5 cartridge container has already been constructed in the form of a ring mounted upon the casing of the weapon, this ring being provided with a number of cartridge chambers. In all the rknown constructions the operating of this weapon is lo effected by the aid -of `a rather long exible connection, such for example as .the device marketed under the name of Bowden cable, which is seized or pulled up by hand or else by the Vaid of a pressure release located at the end of va rather 15 long iiexible tube.

According to this invention a substantial improvement in such weapons secured to a belt is obtainedby providing on the casing of the Weapon a cock or trigger, which may be constructed 2c in the manner of trigger cocks that are usual in guns, revolvers or the like. The trigger may .advantageously be arranged in the end of the casing, so that it moves in a plane horizontally parallel to the front surface of the casing, while :es by means of suitable connections the movement :of the `striker proceeds transversely to this direction, and the ball accordingly also leaves the Weapon transversely to the front surface of the casing.

A further improvement in the weapon according to the invention is obtained by providing it with an absolutely rrn and undisplaceable seat in the belt, and by shaping it like a coupling lock, so that it forms at the same time the closure 35 of the girdle or belt. For this purpose the rear wall of the casing may be provided Vwith the necessary hooks and eyes for securing it to a belt, such as those worn on military service. Alternatively the weapon may be secured, by the aid of suitable fastening means, such as barriers or the like, preferably in a readily releasable manner, but rmly Vand undisplaceably, upon a shoulder belt lock.

Further improvements comprised in this invention relateto the special construction of the members transmitting .the movement of the trigger to the striker and also of the members effect- -ing .the conveyanceof the .cartridge chamber, the return of the striker and of the trigger, the

protection of the weapon, and so forth.

One form of construction of a small fire-arm according to the invention is illustrated by way of example in the accompanying drawings, in

55 which Figure 1 shows the weapon as seen from the front,

Figure .2 is a side View of the Weapon,

Figure 3 shows the interior of the weapon casing after removal of the back wall partly in section,

Figure 4 is a section on the line 4-4 in Fig. l3,

Figure 5 is a section on the line 5 5 in Fig. 3,

Figure 6 is a section on the line 6-6 in Fig. 3,

Figure '7 is a sectionon the line 1-1 in Fig. 3, lo

Figure 8 is a frontview of the weapon with the cartridge chamber removed, and

Figure 9 is a back view of the weapon casing.

In these drawings the reference numeral I denotes the front wall of the casing, which is of lo flat construction, 2 and 3 denote the side walls thereof. 4 is the upper transverse wall, and 5 the lower transverse wall. The weapon casing therefore forms a flat box, open towards the rear. In a rearward direction, that is to say, towards the surface of the body belt, this box is closed by a wall, which is secured to the casing for instance by the aid of lugs V'1, 8, and so forth, engaging upon the casing I. The rear wall is according to the invention preferably provided with a clip 9, through which the belt is passed, With a tongue or prong I0 for engaging in the holes in the body belt, and with eyes II and I2 for engaging the free end of ythe belt. This .construction of the weapon, resembling that of ya coupling lock, may be such that the same admits of being provided in place of an ordinary coupling lock on the leather belt or girdle.

On the casing I of the weapon is secured on the front an annular cartridge chamber I3, by means of screws I4 for example, upon the smooth .shank portion I5 of which the cartridge chamber can rotate. Cylindrical bores I6, Il and so forth in the cartridge chamber serve for the reception of cartridges I8, which are introduced into the cartridge chamber after releasing the screw I4 .and removing the cartridge `chamber from the back. The cartridges may, if desired, ,alternatively be introduced from the side and secured in position by a superposed ring.

vThe ignition of the cartridges is eifected by driving forward a striker pin I9, which in its turn is set in operation by the movement of the trigger 20. vThe movement of the trigger is here transmitted tothe striker pin I9 by the aid of a slidable bar 22. The rotation of the magazine I3 for the purpose of conveying a fresh cartridge in front of the striker pin is likewise elfected by the aid of a loading transporter 2l, also actuated by the movement of the trigger.

striker pin.

In detail the co-operation of the essential members hereinbefore mentioned is accomplished with the assistance of various further auxiliary members in the following manner:- Y

The trigger 29, which is rockable about its pivot 24 in a cavity 23 in the casing wall 2, is provided with three lever-like cams 25, 26 and 2i. After the safety hook 29 has been rocked up by pressure upon the toothed head 29 of the safety device, the locking bar 22 is set free, for the action of the trigger. Now if the trigger 29 is moved in the direction of the arrow A in Figure 3, the cam drives the locking bar 22 forwards in the direction of the arrow, until the cam V25 reaches the position 25' shown in dotted lines. Here the striker pin lever 32, which is rockable about a pivot 33, is pressed by the action of a compression spring 36 into the recess of the locking bar 22 in front of a wedge surface 3|.A t the same time the striker pin I9 goes back into the interior of the casing. Then the spring 30, which has been stressed by the forward moving of the locking bar 22, drivesl the locking bar back. Under these circumstances-the inclined surface 3| of the locking bar pushes against the upper portion of the striker pin lever. The striker pin lever 32 is therefore pushed back in the vdirection of the arrow in Figure 4, and accordingly the tip I9 of the striker pin is thrown forward. It then strikes the bottom of the Ycartridge 35 and discharges the shot. In order to obviate an excessive recoil of the locking bar 22 under the influence of the spring `its movement is limited by a pin 38 projecting into the locking bar recess. Y 1 f The backward Vmovement of the trigger 20 is effected by the action of a blade spring 3S, which bears against the cam 2l. In its backward movement the cam 25 moves away from the end wall or cap 4| of the locking bar Y22, which is rockable Vabout al pivot 4E), and which, after the passage of the cam 25, is returned by a spring 42 into its original position'. The cartridge chamber |3, which, in the closed position, is arrested by a bolt 45 controlled by a spring 43 and provided with arrounded head 44, is transportedrby the trigger cam 26 when the trigger 204is pulled; for the cam 26 bears upon a rotatable arm 46, in which is supportedtheY transport locking bar 27| already mentioned. The transport locking bar 2| acts upon one toothV 4l in a group of teeth projecting rearwards out of the cartridge chamber |3 into a segmental cavity 48 in the casing wall Following the movement of the cam 26, the transport locking bar 2| Vpresses the tooth 41 so far downwardsY that the next cartridge moves into a Vposition in front Yof the In this position the bolt 45, which had been pressed back during the rotary movement of the'cartridgeV chamber, arrests the cartridge chamber afresh. Y The return of the arm 46 and ofthe transport locking bar 2| is then effected by a blade spring 49, which may if desired be made in one piece with the spring 39. The transport locking'bar 2|, which isA so supported in the arm 45 as to be movable by a spring 50, then slips past the nextupper tooth of vthe cartridge chamber I3, and takes up a position in the gap between this tooth and the next one. Thus all the parts of the weapon have returned into their original positions. Upon the head 29 of the safety device being released, the hook 28 of the safety device falls down, so that the weapon is again in the safety position. 5| denotes a spring pin, which enters an aperture 52 in the parts.

rear wall 6 and serves as an arresting means for the rear wall. Y

VThe invention may be modified in construction and design in a variety of ways without departing from the basic idea. The exceedingly fiat shape of the weapon casing, which in other respects may be of any desired design, for instance round or .heXagonaL and which enables the weapon to be constructed and employed as a belt lock, is in any case essential, and is rendered Ypossible by the transverse arrangement of the transmission means between the trigger and the striker bolt and of the charge transporter. Other points of particular importance are: The leverlike construction of the trigger in the manner of the known gun triggers, and the device described for transporting and arresting the cartridge chamber, as Well as for returning the moving The supplying of the cartridges may however if desired be effected in another way, by belts for example, In practice the Weapon may do good service to all officials or other persons employed in watching, for instance factory watchmen, transport conductors, registered letter carriers, cyclists, motor cyclists, and the like.

Instead of ball cartridges this weapon may also be equippedY for firing blank cartridges, percussion caps or the like.

For the purpose of diminishing the recoil, the belt or the rear wall of the casing may be widened orsupported. The weapon may also be provided with automatic release and actuation for a continuoussuccession of shots. Furthermore the weapon can also be employed for shooting paint or other liquid substances.V
